Random Animation question

Hi,

Firstly I would like to add thanks to the many posters on here with excellent informtion for newbies to flash like myself, it is by far the best site for info I have found so far.

With this in mind I would like to ask my first question, and a plea for help from those with greater knowledge than I.

I love the random animation code http://www.kirupa.com/developer/mx/random_motionMX.htm

My question is, is it possible to add to that a direction?

For example I want to use a fish as my movie clip to randomise, this code works absolutly brilliant, apart from when the fish goes left it appears to be swimming backwards! As far as I am aware Reverse is not the most common gear for fish, so is it possible to add something to the code that says if movement = left flip animation horizontally, so the fish always appears to be swimming forward?

Thanks in advance for any help
Tilly
